@Jones1183, try the below possible solutions one-by-one:

• Try restarting your computer and then verifying the integrity of the game cache for Arma 3.

1. Restart your computer and launch Steam
2. From the Library section, right-click on the game and select Properties from the menu.
3. Select the Local files tab and click the Verify integrity of game cache... button.
4. Steam will verify the game's files - this process may take several minutes.

arma3.rpt:

== "E:\Steam\steamapps\common\Arma 3\arma3.exe" -skipIntro -noSplash -cpuCount=8 -exThreads=7 -malloc=tbb4malloc_bi -enableHT -maxmem=2047 -maxvram=2049 -world=empty -connect=5.9.74.118 -port=2322 -port=2322 "-mod=E:\Steam\steamapps\common\Arma 3\@bwa3;E:\Steam\steamapps\common\Arma 3\@ace;E:\Steam\steamapps\common\Arma 3\@adv_urban_rappeling;E:\Steam\steamapps\common\Arma 3\@ares_mod_achilles_expansion;E:\Steam\steamapps\common\Arma 3\@bwa3_comp_ace;E:\Steam\steamapps\common\Arma 3\@CBA_A3;E:\Steam\steamapps\common\Arma 3\@cup_terrains_core;E:\Steam\steamapps\common\Arma 3\@sthud_a3;E:\Steam\steamapps\common\Arma 3\@task_force_radio;E:\Steam\steamapps\common\Arma 3\@xcam_taunus"

-enableHT should be used without -cpuCount=. Please remove either one or both.

-port=2322 is listed twice. One can be removed.

• Alternatively, reset the launch parameters to their default state via the Arma 3 Launcher. Also check under Steam → Arma 3 → Properties → General → Set Launch Options...

• Try repairing the mod(s) via the Arma 3 Launcher:

1. Click "MODS."
2. Click the dropbox arrow next to the mod to repair.
3. Click the "..." icon.
4. Click "Repair."

• Try playing without any mods loaded.

• Try all of the possible solutions listed for 0xC0000005 - ACCESS_VIOLATION on the Arma 3 Unusual process exit article on the Bohemia Interactive Community Wiki.

If the issue persists after trying all of the above possible solutions then use the Arma 3 Launcher to prepare a new troubleshooting report and then upload the report to the feedback tracker for the developers to review.

Hi, @Jones1183

Disable this:

-cpuCount=8 -exThreads=7 -malloc=tbb4malloc_bi -enableHT -maxmem=2047 -maxvram=2049
unload all your mods and try to load them back one by one

also try this

Delete your profile folder (create a backup) a try to start the game.
The file yourprofilename.vars.Arma3Profile must be deleted.
Path: C:\Users\*username*\Documents\Arma 3

https://feedback.bistudio.com/T122979 Heres a link to my thread. I've been having the same crashes since the Apex update. There are a ton of useful things to try there too. Unfortunately I've had no luck, but they may help you.

As for @InfraRedLXIX 's thread:

Also fixed the Unable to init directx by downloading and installing this:

As for the STATUS_ACCESS_VIOLATION, do the following steps:

1. Open Windows Explorer
2. Right Click the C:\ Drive
3. Go to Properties
4. Click the "Security" tab
5. Under the "Group or user names" box, click Edit
6. Click the "Users (PC_NAME\Users)" option inside the "Groups or user names" box
7. Click the box next to the the Full Control Under allow.
8. Repeat for "Administrators (PC_NAME\Administrators)" and "SYSTEM" options.
9. Click OK on the bottom of the box. (If a window pops up with a loading bar like your copying something, then its working)
10. Click OK on the original box that is left

It should now be fixed.
